Preheat the oven to 200 degrees F (100 degrees C). Toss sweet and Yukon Gold potatoes with zucchini, carrot and green onion. Stir cottage cheese with flour, eggs, salt and pepper until well blended; pour over vegetables and stir to combine.

Melt a little Spreadables in a large, nonstick skillet set over medium heat. Scoop 1/4 cup (50 mL) portions of vegetable mixture into skillet; flatten using back of measure. Cook for 5 minutes per side or until browned and cooked through. Transfer pancakes to a baking sheet in oven to hold warm. Repeat with remaining vegetable mixture, adding additional Spreadables to the skillet as needed. Serve pancakes with sour cream and cheese (if using).
